* Added a new module FindSanitizers with new function add_sanitizers to combine all sanitizers in one function instead of adding each one by one. * Code of FindASan.cmake was outdourced into helper functions, so that the code may be used by other sanitizer modules, too. * AddressSanitizer will be used with -O1 now to get a better performance.
